What dimensions are you guys using for your ladder type anti wrap bars. From looking at Sams style they look to be made out of 10" x 4" axle brackets with about 8" in between the link bars and the top bar being about 3' long, that sound about right for what you are running. I have everything I need except the johnny joint for the shackle, guess I will get that from Currie unless anyone else has a better source.

You can use spring bushings at both ends. Just put together a goofy shackle that can twist forward, and side to side.
